I shot a 15 point 900lb+ bull moose in NFL. Totally butchered and shrink wrapped left about 300lbs of meat to take home. The meat was frozen solid and was placed without ice in 3-150 qt coolers. You'll need another cooler for the hide. If you bring back a black bear (I did) you will need a cooler for the bear hide and bear meat if you take that too. Hauled everything home in a 4'x8' enclosed trailer.

It took me two days to get home including the ferry ride (I live in NY). All the meat was fine.
